A Power Study Of A Laboratory Ball Mill, Frederick Clearman

Masters Theses

"Ball milling practice in the ore dressing industry is largely empirical. Although many investigators have worked on various of its phases, the present operating methods are mostly a matter of cut-and-try, with the result that the industry is not guided by its underlying principles. Consequently, practice varies extensively with regard to nearly all conditions of operations. Even in neighboring concentrators such factors as speed, ball charge, and ore load differ in similar ball mills. Since fine grinding is continually becoming of more importance, and often accounts for thirty per cent of the milling cost, it is very necessary that a …

Revision Of The Jefferson City Formation In The Rolla Quadrangle, James Shelley Cullison

Masters Theses

"The geology of the Rolla quadrangle was mapped by Lee in 1912. At that time all the dolomitic strata above the Roubidoux and beneath the Carboniferous formations in this area were placed in the Jefferson City. A more detailed study of the stratigraphy of the whole Ozark region by Ulrich has shown that some of the strata which had been included in the Jefferson City formation on lithologic grounds are not equivalent to the dolomites in the type section at Jefferson City, Missouri"--Introduction, page [1].

The Social And Political Philosophy Of Shelley As Revealed In His Poetry, Eulalie Imogene Powell

Masters Theses

"The interest in a study of the philosophy of Shelley does not lie in the hope of discovering anything new, since there is little in anyone's belief that is without historic parallel. Rather, the sources of such an interest are first, the medium of poetry through which Shelley expressed his belief, and secondly, the transference of these beliefs into the acts of his life. It is to a consideration of the first of these that this paper is limited. Biographical facts will be used only for the elucidation of the theories expressed in his poems. Briefly, the purpose of this …

Laboratory Concentration Of The Missouri Iron Ores Of Iron Mountain And Pilot Knob, Strathmore Ridley Barnott Cooke

Masters Theses

"The purpose of this investigation was to ascertain whether the more important iron ores of Missouri would be amenable to beneficiation to produce high grade concentrates. In the southeastern section of Missouri are found many small deposits of high grade iron ores, and a few large deposits of comparatively low grade ore. The former consist chiefly of red and brown hematite and limonite ores that are in no need of beneficiation. the low grade iron orebodies are relatively large in extent, and, if they could be beneficiated successully [sic] and economically would be of value. Accordingly, the major portion of …

A Study Of The Iodine Content Of Missouri Vegetables And Soils, Charles Jackson Potter

Masters Theses

"Investigations have shown that the iodine content of vegetables, water, and soils has a direct relationship to the goiter incidence of a given region. A few countries, notably New Zealand and Switzerland have made a rather complete survey. In the United States, South Carolina has made the most progress in this direction.

At the present time there are no available records of vegetable and soil analysis for iodine in Missouri. Hunze determined the amount of iodine in waters in Missouri. The connection of his results with the author's results will be seen later.

The present investigation was carried out at …

The Effect Of Various Methods Of Grinding On The Physical Properties Of Unfired Dry Press Brick, Edwin Theodore Harvey

Bachelors Theses

"In the manufacture of dry press brick, the final grinding of the clay is usually done in a dry pan. This is especially true of fire brick made by the dry press method. It is logical to assume that different types of grinding machines will impart different characteristics to the ground clay mix, as regards the grain size variation and the shape of the grains, which in turn will have an effect on the properties of the brick. The purpose of this investigation was to determine what effect different types of grinding methods have on the physical properties of unfired …

The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Degree Of Pressure, Physical Character Of Mix Ingredient, And The Moisture Content Of The Mix, Ferdinand Frederick Netzeband

Bachelors Theses

"In February, 1929, the Dry Press Committee of the National Brick Manufacturers Association, in cooperation with the department of Ceramics of the Missouri School of Mines and Metallurgy, began several investigations relating to dry press ware. This Committee suggested a great number of possible investigations, and are now systematically proceeding along these lines. This investigation has for its object: (1) The transmission of pressure in the dry pressing of typical building brick and fire brick mixes as affected by the degree of pressure; and (2) As affected by the moisture content of the mix. this thesis contains a description of …

A Fire Clay Cement Study, Willard E. Davis

Bachelors Theses

"The purpose of this investigation was to develop a satisfactory boiler setting cement from a semi-flint fire clay. This clay is now being mined and used to make refractory ware by the Wellsville Fire Brick Company, Wellsville, Missouri. It has been my intention of using only those materials which have been used by this company and following the same preparation of the clay, that is, using the machinery which is at present available in the plant"--Introduction, page 3.

Disintegration Of Ozark Plastic Fire Clay In The Drier, Elmer Francis Cirkal

Bachelors Theses

"During the procedure of testing Ozark Plastic Fire clay in 1928-29 a few of the test bars were unintentionally left in a laboratory drier and after some months it was found that these bars were decidedly disintegrated into a powder without any known special treatment...In order to properly investigate the cause of this phenomena it was decided to repeat the experiment under similar conditions so that no error could enter the investigation which would cause any deviation from the results previously obtained "--pages 1 -2.

The Determination Of The Alumina Content In Diaspore And High Alumina Clays, W. D. Keller

Bachelors Theses

"The determination of the alumina in diaspore and kindred high alumina clays has been a problem which has attracted the interest of ceramists and chemists ever since a sample of Missouri diaspore was first sent for analysis to the laboratories of the Missouri School of Mines and Metallurgy in 1917...It is the writer's intention to review in this paper the various published methods for the determination of alumina in high alumina clays and to present a new indirect one that after some months' use in industrial practice, fulfills, in some measure at least, the need outlined above"--Introduction, page 1 -2.

The Lead And Zinc Deposits In The Sedimentary Rocks Of East Tennessee And Southwest Virginia, Joseph Hugh Reid

Professional Degree Theses

"In its geographic and geologic relations this area forms a part of the Appalachian province, which extends from the Atlantic Coastal plain on the East to the Mississippi lowlands on the West and from Central Alabama to Southern New York. All parts of the region thus defined have a common history recorded in its rocks, its geologic structure and its topographic features"--Geography, page 1.

An Engineer's Report Of A Lead And Zinc Mining Property, Ernest Moran

Professional Degree Theses

"Gentlemen: Pursuant to your request, I have analyzed and classified the data relative to the Van Buren Mine of the Lucky Syndicate Mining and Smelting Company and beg to submit the following report. The lease is a lead and zinc mining property consisting of eighty (80) acres more or less..."--Letter to the Wright Mining & Royalty Co Miami, Oklahoma, dated December 9, 1929.

Longface And Longwall Mining Methods Being Tried In Oklahoma Coal Fields, Earl Hollinger Mcalpine

Professional Degree Theses

"Of a number of long wall and long face mining methods in use in Oklahoma mines at this time, I shall outline four in this paper. Two of these methods are in use in mines which are comparatively level. The first of these is in the Kali-Inla mine near Hartshorne. The second is in the Milby-Dow Coal Company mine at Dow. The Mullen Coal Company mine near McAlester and the Hailey-Ola Company mine near Lutie are steep pitching mines"--page 1.
